A process for manufacturing a magnetic pole assembly (10) for a switchable magnet base (12), which magnetic pole assembly has non-magnetic member means (20) and a pair of magnetic pole members (18) coupled to each other, with non-magnetic member means interposed therebetween. Holes (24) are provided in the pair of magnetic pole members in the opposing surfaces thereof, and the non-magnetic member means is formed between the pair of opposing magnetic pole members by using the magnetic pole members as part of the mold, whereby the non-magnetic member means is formed, and at the same time, the non-magnetic member means and the pair of magnetic pole members are coupled into a unitary body by the non-magnetic materials cast in the aforesaid holes. |
